TECHNICAL FIELD

This disclosure relates to implementations of a binocular bridge system.

BACKGROUND

The PVS-14 night vision monocular is in widespread use by warfighters,law enforcement personnel, and the civilian market. The PVS-14 uses asingle image intensifier tube that only provides an image to one eye ofthe user. Cost, size, and weight are key factors that lead to thedevelopment and selection of the PVS-14.

Ocular dominance is the brains tendency to prefer receiving visual inputfrom one eye to the other. Naturally, most people have a dominant eyeregardless of light conditions. However, the non-dominant eye is stillvery important since it is used in conjunction with the dominant eye tosend more visual input to the brain. Consequently, a person can see withone eye, but their field of vision will be restricted, depth perceptioncompromised, and visual-motor abilities reduced.

When performing tasks that require sight, it is imperative that visualinput provided to the brain not be diminished. When performing a taskusing a night vision monocular, the eye engaged therewith will be thedominant eye. This occurs because the eye viewing the image produced bythe night vision monocular is the only eye providing significant visualinput to the brain. When a task needs to be completed rapidly,particularly task being performed during a combat operation, speed canbe a critical factor to success or failure. This is why specialoperations teams have been using dual-tube night vision binoculardevices for decades. Through the use of two image intensifier tubes, anight vision binocular device provides an image to each eye of the userand facilitates binocular vision. Compared to the monocular visionfacilitated by a night vision monocular, the binocular visionfacilitated by a night vision binocular device provides for depthperception, increased visual-motor abilities, and a larger field ofvision.

Unfortunately, the cost of purchasing purpose built dual-tube nightvision binocular devices is prohibitively expensive for many militaryunits, law enforcement agencies, and civilian end users. Therefore, aneed exists for a device that can couple two night vision monoculars(e.g., PVS-14s) already in inventory together, effectively providing theuser with a dual-tube night vision binocular system.

Accordingly, it can be seen that needs exist for the binocular bridgesystem disclosed herein. It is to the provision of a binocular bridgesystem configured to couple two night vision monoculars together,effectively providing the user with a dual-tube night vision binocularsystem, that the present invention is primary directed.

SUMMARY OF THE INVENTION

Implementations of a binocular bridge system are provided. The binocularbridge system is configured to couple two night vision monocularstogether, effectively providing the user with a binocular night visionsystem. The binocular bridge system is configured to mechanicallycollimate the two night vision monoculars paired thereby. This mayminimize, or eliminate, headaches and disorientation that can occur whenusing a night vision system comprising two non-aligned image intensifiertubes.

DETAILED DESCRIPTION

FIGS. 1A-1D, and 2A-2C illustrate an example binocular bridge system 100according to the principles of the present disclosure. The binocularbridge system 100 is configured to couple two night vision monoculars104 a, 104 b together, effectively providing the user with a dual-tubenight vision binocular system. In some implementations, the binocularbridge system 100 may be secured to a helmet, thereby positioning afirst night vision monocular 104 a and a second night vision monocular104 b on the head of a user. In some implementations, the first nightvision monocular 104 a and the second night vision monocular 104 b maybe mounted on a first hinged arm 130 and a second hinged arm 140,respectively, of the binocular bridge system 100 (see, e.g., FIGS. 1Aand 1B). In this way, each night vision monocular 104 a, 104 b, via thehinged arm 130, 140 to which it is attached, can be independentlypositioned by the user. In some implementations, each hinged arm 130,140 may be configured to move the attached night vision monocular 104 a,104 b between at least a first position (e.g., deployed in front of theuser's eye) and a second position (e.g., stowed or unused). In someimplementations, the binocular bridge system 100 may be configured tosimultaneously power, and control the operation of (i.e., turn on/off),the two night vision monoculars 104 a, 104 b mounted thereon.

As shown in FIGS. 2A-2C, in some implementations, the binocular bridgesystem 100 may comprise a bridge 110, a first hinged arm 130 having anobjective alignment ring 132 thereon, a second hinged arm 140 having anobjective alignment ring thereon 142, and two dummy battery inserts 150a, 150 b. Each dummy battery insert 150 a, 150 b is configured to bepositioned within the battery compartment of a night vision monocular104 a, 104 b and conductively connect it to a power source (e.g., abattery) housed within the bridge 110. In some implementations, thebinocular bridge system 100 may further comprise a remotely positionedbattery pack that may be conductively connected to the bridge 110 via acable.

As shown in FIGS. 2A-2C and 3, in some implementations, the bridge 110of the binocular bridge system 100 may comprise a master control switch111 (e.g., an on/off switch), a battery storage compartment 112, aninterface shoe 113 (e.g., a dovetail interface) configured to connectthe system 100 to a helmet mount, and/or an interior compartment 120containing a printed circuit board 122 (PCB).

As shown in FIGS. 1A and 1B, in some implementations, the master controlswitch 111 may be configured to act as an on/off switch for both nightvision monoculars 104 a, 104 b conductively connected thereto via thedummy battery inserts 150 a, 150 b.

As shown in FIGS. 1E and 3, the master control switch 111 may comprise aswitch 114, a washer 115, a threaded nut 116, and a knob 117. In someimplementations, the washer 115 may be larger in diameter than theswitch 114. In some implementations, the threaded nut 116 may bethreadedly secured to a portion of the switch 114 and used to secure thewasher 115 against the face of the switch 114 (see, e.g., FIG. 1E). Insome implementations, the knob 117 may be operably connected to therotating shaft of the mechanical switch 114 (see, e.g., FIG. 1E). Insome implementations, an assembly comprised of the mechanical switch114, the washer 115, and/or the threaded nut 116 may be coated in anadhesive (e.g., silicone) and positioned within an opening in the bridge110 (see, e.g., FIG. 1E). In this way, the master control switch 111 maybe secured within the opening in the bridge 110. In someimplementations, the knob 117 may be configured to rotate the shaft ofthe mechanical switch 114 between at least a first position (e.g., an“on” position) and a second position (e.g., an “off” position). In thisway, the knob 117, and thereby the mechanical switch 114, may be used toselectively energize (i.e., turn on/off) the night vision monoculars 104a, 104 b conductively connected thereto via the dummy battery inserts150 a, 150 b.

In some implementations, the washer 115 of the master control switch 111may not be larger in diameter than the switch 114.

As shown in FIG. 3, in some implementations, the battery storagecompartment 112 of the bridge 110 may be configured to hold one or morebatteries therein. In some implementations, the power source(s)contained within the battery storage compartment 112 may be conductivelyconnected to both dummy battery inserts 150 a, 150 b via the mastercontrol switch 111. In this way, the master control switch 111 may beused to selectively energize the conductively connected night visionmonoculars 104 a, 104 b simultaneously.

As shown in FIG. 3, in some implementations, the battery storagecompartment 112 may comprise a battery housing 118 and a battery cap119. In some implementations, the battery housing 118 may be positionedwithin an opening in the bridge 110. In some implementations, thebattery housing 118 may be configured to contain one or more batteriestherein. In some implementations, the battery cap 119 may be configuredto threadedly secured to the open end of the battery housing 118. Inthis way, one or more batteries may be retained within the batteryhousing 118.

As shown in FIG. 1C, in some implementations, the interface shoe 113 maybe removable connected to the bridge 110 by one or more fasteners. Insome implementations, a fastener may be inserted through each opening113 a extending through the interface shoe 113 and threadedly receivedwithin a corresponding threaded opening in the bridge 110 (see, e.g.,FIG. 3). In this way, the interface shoe 113 may be removably connectedto the bridge 110 of the binocular bridge system 100.

As shown in FIGS. 1B and 3, in some implementations, the interiorcompartment 120 of the bridge 110 may be enclosed by a plate 121. Inthis way, the PCB 122 contained therein may be protected from theenvironment (e.g., water).

In some implementations, the PCB 122 may comprise a voltage divider 124configured to provide an output voltage to the conductively connectednight vision monoculars 104 a, 104 b that is a fraction of the inputvoltage provided by the power source (e.g., one or more batteries)contained in the battery storage compartment 112. In someimplementations, the PCB 122 may be conductively connected to the powersource contained in the battery storage compartment 112 and the dummybattery inserts 150 a, 150 b. In this way, the PCB 122 is able toprovide an output voltage (i.e., power) to the attached night visionmonoculars 104 a, 104 b.

As shown in FIGS. 1A and 1B, the first hinged arm 130 and the secondhinged arm 140 may be configured so that the first night visionmonocular 104 a and the second night vision monocular 104 b,respectively, may be removably secured thereto by a threaded fastener126 (e.g., a screw). In some implementations, the objective alignmentring 132 of the first hinged arm 130 and the objective alignment ring142 of the second hinged arm 140 may be configured to fit about theobjective lens locking ring of an attached night vision monocular 104 a,104 b (see, e.g., FIG. 1C). In this way, the front end of the attachednight vision monocular 104 a, 104 b may be supported. Also, in someimplementations, the objective alignment rings 132, 142 may beconfigured to position (i.e., mechanically collimate) the monoculars 104a, 104 b so that the objective lenses thereof are in alignment (i.e.,parallel) with each other (see, e.g., FIGS. 1C and 2C).

As shown in FIGS. 1A and 2B, the first hinged arm 130 may be coupled tothe bridge 110 by a hinge 134. In this way, the first arm 130 may bemoved (or swing) between at least a first position and a secondposition. In some implementations, the proximal end of the first hingedarm 130 may be coupled to the bridge 110 by two pivot pins 131.

As shown in FIG. 2B, in some implementations, the first hinged arm 130may include an opening 135 near the distal end thereof for a threadedfastener 126 to extend through. In some implementations, the threadedfastener 126 (e.g., a flat head screw) may be inserted through theopening 135 of the first hinged arm 130 and screwed into the threadedhole in the housing of the first night vision monocular 104 a (see,e.g., FIG. 1C). In this way, the night vision monocular 104 a may besecured to the first hinged arm 130 of the binocular bridge system 100.

As shown in FIGS. 2B and 3, in some implementations, the objectivealignment ring 132 extends from the first hinged arm 130 of thebinocular bridge system 100. In some implementations, the objectivealignment ring 132 includes a cantilever 132 a extending therefromconfigured to be removably secured by, one or more, threaded fastenersto a cantilever 137 extending from a front side of the first hinged arm130. In some implementations, as shown in FIGS. 2A and 2B, thecantilever 132 a of the objective alignment ring 132 and the cantilever137 of the first hinged arm 130 may be secured together in anoverlapping fashion. In some implementations, the underside of thecantilever 132 a extending from the objective alignment ring 132 mayinclude an abutment 139 against which the front end of the cantilever137 extending from the first hinged arm 130 rest.

As shown in FIGS. 1A and 2A, the second hinged arm 140 may be coupled tothe bridge 110 by a hinge 144. In this way, the second hinged arm 140may be moved (or swing) between at least a first position and a secondposition. In some implementations, the proximal end of the second hingedarm 140 may be coupled to the bridge 110 by two pivot pins 141 (see,e.g., FIG. 3). In some implementations, the second hinged arm 140 may beconfigured to contour about the housing of a night vision monocular 104b (see, e.g., FIG. 2C).

As shown in FIGS. 2A and 3, in some implementations, the second hingedarm 140 may include an opening 145 near the distal end thereof for athreaded fastener 126 to extend through. In some implementations, thethreaded fastener 126 (e.g., a flat head screw) may be inserted throughthe opening 145 of the second hinged arm 140 and screwed into thethreaded hole in the housing of the second night vision monocular 104 b.In this way, the night monocular 104 b may be secured to the secondhinged arm 140 of the binocular bridge system 100.

As shown in FIGS. 2A and 3, in some implementations, the objectivealignment ring 142 extends from the second hinged arm 140 of thebinocular bridge system 100. In some implementations, the objectivealignment ring 142 includes a cantilever 142 a extending therefromconfigured to be removably secured by, one or more, threaded fastenersto a cantilever 147 extending from a front side of the second hinged arm140. In some implementations, as shown in FIGS. 2A and 2B, thecantilever 142 a of the objective alignment ring 142 and the cantilever147 of the second hinged arm 140 may be secured together in anoverlapping fashion. In some implementations, the underside of thecantilever 142 a extending from the objective alignment ring 142 mayinclude an abutment 149 against which the front end of the cantilever147 extending from the second hinged arm 140 rest.

As shown in FIG. 1A, in some implementations, the first dummy batteryinsert 150 a and the second dummy battery insert 150 b may be configuredto conductively connect the first night vision monocular 104 a and thesecond night vision monocular 104 b, respectively, to the master controlswitch 111, battery storage compartment, and/or the PCB 122 stored inthe interior compartment 120 of the bridge 110. In some implementations,a first conductive cable 180 a and a second conductive cable 180 b maybe used to conductively connect the first dummy battery insert 150 a andthe second dummy battery insert 150 b, respectively, to the mastercontrol switch 111, the battery storage compartment 112, and/or the PCB122 stored in the interior compartment 120 of the bridge 110 (see, e.g.,FIG. 1C).

As shown in FIGS. 4A-4C, in some implementations, each dummy batteryinsert 150 a, 150 b may comprise a top cap 152, a rotating cap 154, anegative contact 156, a cylindrical shaft 158, an alignment washer 160,and/or a positive contact 162. In some implementations, a first end of aconductive cable 180 a, 180 b may be positioned within a dummy batteryinsert 150 a, 150 b and a first wire thereof conductively connected tothe negative contact 156 and a second wire thereof conductivelyconnected to the positive contact 156. In this way, an electrical cable180 a, 180 b may be used to conductively connect a dummy battery insert150 a, 150 b, and thereby a night vision monocular 104 a, 104 b, to themaster control switch 111, the battery storage compartment 112, and/orthe PCB 122 of the binocular bridge system 100.

As shown in FIGS. 4A-4C, in some implementations, the distal end of thetop cap 152 may be configured (i.e., threaded) so that the factorybattery cap of a night vision monocular 104 a, 104 b may be threadedlysecured thereon. In this way, the factory battery cap may be retained.In some implementations, the top cap 152 may comprise a guide groove 152a through which a conductive cable 180 a, 180 b extends (see, e.g., FIG.1C). In some implementations, the guide groove 152 a in the top cap 152may extend through a portion of the base member 152 b thereof (see,e.g., FIG. 4B).

As shown in FIGS. 4A and 4B, in some implementations, the rotating cap154 may be rotatably positioned between the top cap 152 and the negativecontact 156 of a dummy battery insert 150 a, 150 b. In someimplementations, the rotating cap 154 may be configured to threadedlyattach to the battery compartment of a night vision monocular device 104a, 104 b (see, e.g., FIG. 1C). In some implementations, the rotating cap154 may include a central opening 154 a that extends therethrough.

As shown in FIG. 4B, in some implementations, the cylindrical shaft 158may comprise a first end having an annular shoulder 164 thereon, alongitudinally extending channel 166, and/or a longitudinally extendingcentral bore. In some implementations, when a dummy battery insert 150a, 150 b is assembled, a portion of the first wire that is secured tothe negative contact 156 may be nested within the longitudinallyextending channel 166 of the cylindrical shaft 158. In someimplementations, a portion of heat-shrink tubing may be used to insulatethe first wire nested in the channel 166 of the cylindrical shaft 158(see, e.g., FIG. 4C).

As shown in FIG. 4B, in some implementations, the negative contact 156may comprise a generally circular base 156 a having a cylindrical boss156 b extending upwardly therefrom, and a central opening 156 c thatextends therethrough. In some implementations, the circular base 156 aof the negative contact 156 may be larger in diameter than thecylindrical boss 156 b thereof. In some implementations, the cylindricalboss 156 b may be smaller in diameter than the central opening 154 athat extends through the rotating cap 154. In this way, the rotating cap154 is able to rotate about the cylindrical boss 156 b of the negativecontact 156. In some implementations, the negative contact 156 may befabricated from nickel plated aluminum. In some implementations, thenegative contact 156 may be fabricated from any material, or combinationof materials, suitable for use as an electrical contact.

In some implementations, the alignment washer 160 may be configured tocentrally position a dummy battery insert 150 a, 150 b within thebattery compartment of a night vision monocular 104 a, 104 b. In thisway, the positive contact 162 of a dummy battery insert 150 a, 150 bremains in conductive contact with the positive contact of the batterycompartment into which it has been positioned.

As shown in FIG. 4B, in some implementations, the positive contact 162may comprise a circular base 162 a having a cylindrical shaft 162 bextending therefrom. In some implementations, the circular base 162 a ofthe positive contact 162 may be larger in diameter than the cylindricalshaft 162 b thereof. In some implementations, the positive contact 162may be fabricated from nickel plated aluminum. In some implementations,the positive contact 162 may be fabricated from any material, orcombination of materials, suitable for use as an electrical contact.

In some implementations, once a first end of a conductive cable 180 a,180 b has been positioned within the central bore 168 of the cylindricalshaft 158 and a conductive wire thereof secured (e.g., soldered) to boththe positive contact 162 and the negative contact 156, the followingsteps may be used to assemble a dummy battery insert 150 a, 150 b:

Initially, insert the first end of the cylindrical shaft 158 into theopening 156 c extending through the negative contact 156 so that thecircular base 156 a thereof comes to rest on the shoulder 164 of thecylindrical shaft 158.

Then, in some implementations, position the rotating cap 154 over thenegative contact 156 so that the cylindrical boss 156 b thereof extendsthrough the opening 154 a in the rotating cap 154.

Next, in some implementations, position the top cap 152 over therotating cap 154 so that the two fastener channels 153 a, 153 b thereofare aligned with the threaded openings in the negative contact 156.

Then, in some implementations, insert one fastener into each fastenerchannel 153 a, 153 b extending through the top cap 152 and threadedlysecured it within the aligned threaded opening in the negative contact156. In some implementations, when assembled, the top cap 152 and thenegative contact 156 do not impinge on the rotation of the rotating cap154. In this way, the rotating cap 154 may be used to secure a dummybattery insert 150 a, 150 b within the battery compartment of a nightvision monocular 104 a, 104 b without placing torque on the conductivecable 180 a, 180 b extending through the guide groove 152 a in the topcap 152.

Next, in some implementations, insert the second end of the cylindricalshaft 158 into the central opening 160 a extending through the alignmentwasher 160 (see, e.g., FIG. 4A).

Then, in some implementations, insert the cylindrical shaft 162 b of thepositive contact 162 into the opening of the central bore 168 in thesecond end of the cylindrical shaft 158 of a dummy battery insert 150 a,150 b. In this way, the positive contact 162 may be secured to thecylindrical shaft 158 (see, e.g., FIG. 4A).

As shown in FIGS. 1C, 1D, and 3, in some implementations, the bridge 110of the binocular bridge system 100 may further comprise a connectorsocket 170 (e.g., a LEMO connector) configured to interface with theconnector plug (e.g., a LEMO connector) of the cable extending from aremotely positioned power source (e.g., a battery pack). In someimplementations, the connector socket 170 may be configured toconductively connect the remotely positioned power source to the mastercontrol switch 111 and/or the PCB 122 of the binocular bridge system100. In this way, a power source other than what is housed in thebattery storage compartment 112 of the bridge 110 may be used to powerthe night vision monoculars 104 a, 104 b conductively connected to thebinocular bridge system 100.

In some implementations, the binocular bridge system 100 may not includea connector socket 170.

In some implementations, the connector socket 170 may be positionedwithin a bore extending through an extension 172 of the bridge 110. Insome implementations, a portion of the connector socket 170 may extendfrom a first end of the bore and a cover 174 may be used to seal thesecond end of the bore (see, e.g., FIGS. 1C and 1D).

In some implementations, once the first night vision monocular 104 a andthe second night vision monocular 104 b have been secured to the firsthinged arm 130 and the second hinged arm 140, respectively, of thebridge 110 and the first dummy battery cell 150 a and the second dummybattery cell 150 b have been secured in position within the batterycompartment of the first night vision monocular 104 a and the secondnight vision monocular 104 b, respectively, the power switch of eachnight vision monocular 104 a, 104 b should be turned to the “on”position. In this way, the master control switch 111 is able toselectively energize (i.e., power) both night vision monoculars 104 a,104 b simultaneously. Succinctly put, placing the power switch of bothnight vision monoculars 104 a, 104 b in the “on” position closes theirinternal circuits thereby allowing the master control switch 111 tosimultaneously remove or restore the conductive path between a powersource (e.g., a battery stored in the bridge 110 or a remotelypositioned battery pack) and both night vision monoculars 104 a, 104 b.

Although not shown in the drawings, it will be understood that suitablewiring connects the electrical components (e.g., the master controlswitch 111, the battery storage compartment 112, the PCB 122, the firstdummy battery insert 150 a, the second dummy battery insert 150 b,and/or the connector socket 170) of the binocular bridge system 100disclosed herein.

In some implementations, the bridge 110 and/or the interface shoe 113may be fabricated from polyoxymethylene (POM). In some implementations,the bridge 110 and/or the interface shoe 113 may be fabricated from anymaterial (e.g., aluminum), or combination of materials, suitable for useas part of a binocular bridge system 100.

In some implementations, the hinged arms 130, 140, the objectivealignment rings 132, 142, and/or the pivot pins 131, 141 may befabricated from aluminum. In some implementations, the hinged arms 130,140, the objective alignment rings 132, 142, and/or the pivot pins 131,141 may be fabricated from any material, or combination of materials,suitable for use as parts of a binocular bridge system 100.

It is important to note that, in some implementations, no permanentmodification need be made to a night vision monocular 104 a, 104 b inorder to use it in conjunction with a binocular bridge system 100constructed in accordance with the present disclosure.

As shown in FIGS. 1C and 1D, the night vision monoculars 104 a, 104 bused in conjunction with the binocular bridge system 100 are AN/PVS-14s.It should be understood that, in some implementations, othercommercially available night vision monoculars may be used inconjunction with the binocular bridge system 100. Also, in someimplementations, the hinged arms 130, 140 and/or the dummy batteryinserts 150 a, 150 b may be configured to work with other commerciallyavailable night vision monoculars.
